Precipitation

Addition of conc. HCl to saturated Bacl2 solution precipitates Bacl2 ; because of the following reason : (a) It follows from Le Chatelier's principle (b) Of common-ion effect (c) Ionic product (Ba++)(cl) remains constant in a saturated solution (d) At constant temperature, the product (Ba2+)(cl-)2 remains constant in a saturated solution:
